Engine Performance problem
1993 Lexus LS 400 V8 Two Wheel Drive Automatic 217000 miles
motor is a 1uz-fe v8 overhead cam 32 lexus. Car has been maintained properly throught the years was running Great! All of a sudden on the way home from work it loses half it's power. It accelerates fine in park but notice some things engine sounds muffeled. And a bad smell. And rattle on the right side of engine compartment. Sound maybe coming from underneath the car. It doesn't really act like a normal misfire or plug. Acts like it's running on half the cylinders. Can the cat conver cause this kind of loss? I was able to reaCH Hwy speed but sluggishly.
